A recording of an eerie cell phone chat between Michael Jackson and his personal physician was played to jurors as Dr. Conrad Murray's involuntary manslaughter trial got underway in Los Angeles on Tuesday.
Prosecutor David Walgren, Los Angeles' Deputy District Attorney, played the tape during a highly-charged morning in court, during which he also showed showed jurors a photo of Jackson's lifeless body on a gurney.
The King of Pop died of an overdose of anesthetic Propofol and Walgren and his team hope to prove that Murray was the man who administered the fatal injection in June, 2009.
The pop superstar's slurred voice was unrecognizable in the audio recording retrieved from Murray's cell phone, and never played in public.
Walgren insisted the singer was under the influence during the conversation about his upcoming This Is It comeback shows.
The prosecutor stated that the audio alone should have been a red flag for his doctor, Murray, who should have known better than to continue giving Jackson Propofol injections.
Jackson's parents and siblings LaToya, Janet, Jermaine, Randy and Tito were present in court as the trial began.
Murray arrived with his mother.
The doctor has pleaded not guilty to involuntary manslaughter. His legal team maintains Jackson injected himself with a lethal dose of Propofol for pain relief in a desperate bid to cure his insomnia.
